Vulnerability of High Diversity Habitats to Introduced Species

This Issue focuses on a research article by Stohlgren et al. (2003) and two responses to it that were published in Frontiers in Ecology and the Environment. The article discusses the ecology of invasive species and the vulnerability of high diversity communities to invasives. Students, like many others, might assume that habitats with low plant diversity are more vulnerable to invasions of non-native plants than ones with high plant diversity. In contrast, Stohlgren et al.’s (2003) data show just the opposite. These data, plus subsequent comments and data in the “Write Back” section of Frontiers, allow students to explore questions about possible relationships between diversity of native species and a community’s vulnerability to non-natives, effects of scale on the correlation of native and non-native plant diversity, and why scientists might disagree about these data and their interpretations.

Pedagogical Use Description Frontiers Issues are designed to help faculty use a Frontiers article in the classroom. The Stohlgren et al. (Frontiers, 2003) paper can be used to discuss many ecological topics, including: invasive species, species diversity, and community vulnerability to invasives. This article can also be used to address the misconception that correlation signifies cause.
